v0.6

Breaking changes:

• datastore_storage:
  • DatastoreStorage: add new required ndb_client kwarg to constructor, used to get new context in lexrpc websocket subscription handlers that run server methods like subscribeRepos in separate threads (snarfed/lexrpc#8).
  • DatastoreStorage.read_blocks_by_seq: if the ndb context gets closed while we're still running, log a warning and return. (This can happen in eg flask_server if the websocket client disconnects early.)
  • AtpRemoteBlob: if the blob URL doesn't return the Content-Type header, infer type from the URL, or fall back to application/octet-stream (bridgy-fed#1073).
• did:
  • Cache resolve_plc, resolve_web, and resolve_handle for 6h, up to 5000 total results per call.
• storage: rename Storage.read_commits_by_seq to read_events_by_seq for new account tombstone support.
• xrpc_sync: rename send_new_commits to send_events, ditto.
• xrpc_repo: stop requiring auth for read methods: getRecord, listRecords, describeRepo.

Non-breaking changes:

• did:
  • Add HANDLE_RE regexp for handle validation.
• storage:
  • Add new Storage.tombstone_repo method, implemented in MemoryStorage and DatastoreStorage. Used to delete accounts. (bridgy-fed#783)
  • Add new Storage.load_repos method, implemented in MemoryStorage and DatastoreStorage. Used for com.atproto.sync.listRepos.
• util:
  • service_jwt: add optional aud kwarg.
• xrpc_sync:
  • subscribeRepos:
    • Add support for non-commit events, starting with account tombstones.
    • Add ROLLBACK_WINDOW environment variable to limit size of rollback window. Defaults to no limit.
    • For commits with create or update operations, always include the record block, even if it already existed in the repo beforehand (snarfed/bridgy-fed#1016).
    • Bug fix, populate the time each commit was created in time instead of the current time (snarfed/bridgy-fed#1015).
  • Start serving getRepo queries with the since parameter. since still isn't actually implemented, but we now serve the entire repo instead of returning an error.
  • Implement getRepoStatus method.
  • Implement listRepos method.
  • getRepo bug fix: include the repo head commit block.
• xrpc_repo:
  • getRecord: encoded returned records correctly as ATProto-flavored DAG-JSON.
• xrpc_*: return RepoNotFound and RepoDeactivated errors when appropriate (snarfed/bridgy-fed#1083).
